TR8: IP Results Increase Scale of Walparuta Copper-Gold System

Tarrina Resources announced highly positive Induced Polarisation (IP) survey results from its Walparuta Copper-Gold Project in South Australia, confirming a large-scale IOCG system extending over 4-5 km of strike and to depths of 350-500m. The survey identified numerous strong chargeability anomalies, with several exceeding 70 mV/V, which correlate well with existing magnetic, gravity, and copper-gold soil anomalies, significantly upgrading the project's discovery potential. These integrated geophysical targets define multiple high-priority drill targets, and the company plans to commence its maiden drill campaign once approvals are received.

ORP: Drilling Defines Highly Prospective Redox Corridor at Frome

Orpheus Uranium Limited has completed its inaugural drilling program at the Erudina Uranium Prospect within the Frome Project in South Australia, identifying highly prospective redox corridors. The program confirmed geological models for sedimentary-style uranium mineralization and refined four target areas for follow-up exploration. While the reported grades are modest and below economic thresholds, the results provide a strong basis for advancing the project towards defining an Exploration Target.

COD: Positive Cobalt Flotation Results at Elizabeth Creek

Coda Minerals has reported positive laboratory flotation results for cobalt at its Elizabeth Creek Project in South Australia. The testwork demonstrated that up to 83% of cobalt remaining after whole-ore chloride leaching can be recovered into a high-grade concentrate (1.48% Co) with a low mass pull (4.0%). These preliminary results open a pathway to potentially include cobalt revenue, which was previously excluded, into the project's economics, though further testwork and capital expenditure assessment are required.

Drill Results: New Copper Discoveries - Manna Hill

Cobra Resources plc announced new copper discoveries at its Manna Hill project in South Australia, with initial analytical results from ongoing slim-line Reverse Circulation drilling. Highlights include 32m at 0.7% copper from 52m in porphyry-style alteration and 58m at 0.46% copper from 12m in a newly discovered skarn. These results extend known mineralization, identify new zones, and suggest potential for a larger porphyry system, leading to an expansion of the current drill program.
